TUBE-CLEANER.

To all whom it may concern:

Be it known that I, WILLIAM D. FULLER, a citizen of the'United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Tube-Cleaners, of which the following is a specifioation,reference being hadtherein to the accompanying drawings.

My invention relates to tube cleaners and more particularly to a rotary cleaner having a swinging'tool or tools acting by centrifugal force; 1 i

My invention contemplates a device for the cleaning or dislodging of scale or other deposits from the exterior as 'well as the interior of tubes, and is-especially adapted for cleaning boiler tubes, although it may be used for other purpo'ses' The object of my'inven'tion is to provide an improved cleaner of few parts, simple, strong and durablethat can be readily assembled and easily taken apart, the parts being so associated intheir operative relation as to give the greatest efliciency.

In devising a cleaner the problem is presented of providing a device of such limited dim'ensionsas to operate within a tube' and yet give tothe tool or tools suffi'cientaction as toeificiently do the work. This I have accomplished by providing a rotary body having pivoted thereto a single arm swinging alone in a given plane so asto cut the aXis of the body; said arm having pivoted thereto upon a single'pivot a tool or tools adapted to swing across the axis of-the body. i

It will be seen that by the use of a single arm in a given planeunobstructed by other arms operating in the same plane the'arm can be given a greater length or throw'to increase the forceand efficiency of the tool it carries; and further the use of a single arm in a given plane instead of a plurality of arms each having. a tool pivoted thereto permits the employment of a tool or tools 'of relatively large dimensions pivoted. to a single pivot'on said arm'to swing across the axis of the body, whereby additional force is given to the blow delivered by, the tool or tools. Furthermore in this construction the arm and tool are not only given agreater radial throw; but by reason of their increased dimensions, made possible by their I Specification of Letters Patent. Patented July 20, 1915, Application filed April 5, 1913. Serial no. 759,197. r

novel arrangement and cooperation, the arm and tool or tools can be made heavier, which not only increases the force oftheir action but addsgreatly to their strength and durability.

The arm may be limited to' swing into operative position on'one'side only of the cleaner; but I preferably arrange it to swing into operative position on op osite sides, for this not only increases its e ciency,but permits its use with a right or left hand drive. 1 r

' My invention contemplates and the use of the 'term toolor=tools includes any form of a hammering orfcutting tool pivoted to swingacross the aXis of the body of the cleaner by a dual swinging movement such as I have described.

The tool may be in the form of a disk having'a plainortoothe'dperiphery; or it may be made cone-shaped with peripheral teeth. But I preferably employ aplurality of tools pivoted toasingle pivot andspaced apart in the plane of their movement so that like a wagon wheel without its felly each toolwill strike and rebound giving it a very forceful and efficient hammering or hammering and cuttingtactionr 1 Inthe development of my invention .1 triedout the device with a singleand various numbers of'tools and while I obtained the best results with three and four tools spaced. apart asstated, I do not wish to be understood as limiting myself to any pare ticular number. a v 1 The tools may have plain surfaces to act as hammers. orthey may be formed with teeth to cut as .well as hammer; and for use in light scale rotating cutters pivoted to the tool may be employed. These and other features of myinvention will be disclosed in the constructions and combinations .hereinafter more particularly describedand set forth in the claims. I

Referring to the accompanying drawings Figure '1 illustrates one form; ofmy cleaner shown attached to a motorand, disposed within a tube. Fig. 2 is an end view of the cleaner with. the tool centrally disposed in its relation to the body. Fig. 3 is a section onlthe line 33 of-Fig. 2., Fig. 4 is an end view of the cleaner with the tool at the extreme limit of its throw, to. one sideof the ios body andFig. 5 is a like view with thetool at the extreme limit of its throw to the opposite side of the body. Fig. 6 is a section on the line 6-6 of Fig. 7 showing a plurality of cutter wheels on the tool. Fig. 7 is a section on the line 77 of Fig. 6. Fig. 8 is an end View of a tool formed as a cone cutter. Fig. 9 is a section on the line 99 of Fig. 8. Fig. 10 is an end view of a tool in the form of a plain disk. Fig. 11 is a section on the line 1111 of Fig. 10. Fig. 12 is an end view of a tool in the form of a toothed disk. Fig. 13 is asection on the line 1313 of Fig. 12. Fig. 1a is an end view showing a plurality of tools joined to a single hub. Fig. 15 is a side elevation of Fig. 14. Fig. 16 shows a recess to limit the operation of the tool to one side and Fig. 17 a like view showing recess to limit the operation of the tool to the opposite side.

Like numerals represent the same parts in the several views.

In the drawings 1 represent a tube in which there is disposed in operative position, a rotary motor 2 which may be of any suitable construction, having a supply conduit 3 and a shaft 4. A body 5 having a screw-threaded opening 6 to secure the same to the shaft 4 is provided on its opposite side with a recess 7 in which an arm 8 is pivoted to swing on a pin 9, preferably formed integrally therewith, journaled in an opening in said body and held in place by a nut 10 which is secured against being jarred loose by a cross-pin 11.

Tools 12 spaced apart and preferably joined integrally with a hub 13 as shown, swing upon a pivot pin 14 secured within an opening a in the free end of the arm 8 by a cross-pin 15 extending through an opening I) in said arm and pin. The pin 1 1 is provided with a head 16 to hold the tools in place; and the cross-pin 15 is provided with a head 17 seated in a recess of the arm 8 and abutting the wall of the recess 7 whereby said cross-pin is held in place.

The side walls of the recess. 7 limit the movement of the arm 8; and in Figs. 2, 4 and 5 this recess is shown of such dimensions that the tools will swing into operative position on opposite sides of the body whereby the cleaner may be driven with either a right or left hand drive, and the maximum throw with the greatest force to the blow of the tools is given. In Fig. 16 the recess 7 limits the throw of the tools into operative position on one side only of the body; and in Fig. 17 the recess 7 limits the throw of the tools to the opposite side; but as heretofore stated and for the reasons given the recess 7 of Figs. 2, 4 and 5 is the preferred form.

To assemble the cleaner, the tool is placed upon its pivot pin,the pin is then inserted in the opening a of the arm 8, the cross-pin 15 is then inserted, the arm 8 is then placed in the recess 7 with its pivot pin 9 extending through the opening in the body where it is secured by the nut 10 and the crosspin 11.

It will be understood that the form or type of the tools employed may be varied to suit the character of the work; and with that end in view, while the pin upon which the tools swing may be varied to adapt it to the particular tool, that portion which projects into and is secured in the opening a of the arm 8 is of uniform size to fit said opening and is provided with an opening Z) for the cross-pin 15, so that one type of tools may be substituted for another as may be desired.

In Figs. 14 and 15 cutting tools 12 are pivoted to swing upon a pin 141 secured in the opening a of the arm 8 in like manner as the tools 12 as heretofore described.

. In Figs. 6 and 7 the tool 18 is shown with recesses 19 in each of which there are pivoted on pins 20 a plurality of cutter wheels 21, said pins having enlarged ends 22 screwthreaded into an opening in the tool as shown, and held from jarring loose by a wearing plate 23. Said tool is pivoted to swing on a pin 24: having a reduced end 24E of a size to fit the opening a of the arm 8 and provided with an opening for the crosspin 15 and secured in like manner as heretofore described.

Figs. 8 and 9 disclose a cone cutting tool 25 pivoted on a pin 26 having a reduced end 26 suitable to be secured in the opening a of the arm 8 as heretofore described.

Figs. 10 and 11 show a plain disk 27 pivoted on a pin 27 suitable to be secured in the opening a of the arm 8 and Figs. 12 and 13 disclose a cutter disk 28 pivoted on a pin 28" suitable to be secured within the opening a in the arm 8 as heretofore described.

The tools with cutting teeth are especially adapted for use in cleaning scale from the interior of water tubes, while those having plain surfaces are employed in fire tubes to dislodge by their hammering action the scale adhering to the outside surface of the tubes, although they will give efficient service in cleaning water tubes.

Having thus described my invention I claim 1. In a tube cleaner, a rotary body having a single transversely extending arm in front of said body pivoted at one end thereto and proportioned to swing upon its pivot across the longitudinal axis of said body and a tool or tools in front of said arm carried by the free end thereof, substantially as described.

2. In a tube cleaner, a rotary body having a single transversely extending arm in front of said body pivoted at one end thereto and a tool or tools in front of said arm pivoted to the free end thereof, said tool or tools bemove upon their respective pivots across the longitudinal axis of said body, substantially as described.

4. In a tube cleaner, a rotary body having a single transversely extending arm in front of said body pivoted at one end thereto and tools spaced apart and terminating in a central hub in front of said arm pivoted to the free end thereof and proportioned to turn upon their pivot across the longitudinal axis of said body, substantially as described.

5. In a tube cleaner, a rotary body having a single transversely extending arm in front of said body pivoted at one end there- I to and a tool having rotary cutters pivoted thereto in front of said arm, said tool being pivoted to the free end of said arm, said arm being free to swing said tool in position to turn upon its pivot across the longitudinal axis of said body, substantially as described.

6. In a tube cleaner, a rotary body adapted to be secured to driving means and having a triangular recess in its forward face'extending 1n a plane transverse to the arms of'sald body, an arm pivoted to swing within said recess and be protected thereby, and a tool or tools pivoted to said arm, substantially as described.

7 In a tube cleaner, a rotary body adapted to be secured to driving means and having a recess in its forward face with an arm therein extending transversely tothe axis of the body and pivoted at one end thereto to swing by centrifugal force, a tool and a pivot therefor, a cross-pin to hold said pivot within an opening in the free end of said arm,,

said cross-pin being retained in place by a wall of said recess, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.
